The trip meter and light just stopped.What manual should I purchase to find these problems
.I been advised it is the fuse links, how does one locate fuse links.These two items was repaired when I purchased the car new.It now has 78000 miles and back again.Now as an old man I find things difficult to repair.Thanks ahead,I appreciate input.William Russell.
A factory workshop manual will help you with the problems
ac moving from cool to heat means that the ac compressor is cycling from the thermostast setting
if you have climate control in use , that indicates a problem climate control module
SOURCE: climate control codes
I have checked every site that I can think of and run the question many times, unable to get the procedure, maybe a nice tech at the local dealer will help u out, if not I guess buying a service manual might be your only option. I am a retired Ford mechanic, I did almost all the AC work, I never found this problem was a control head issue, it was always the blend door electric motor, I think you can see it from the glove box if you remove the liner.

ok i am going to assume by "holding the turn sinal back" that means the high beams are on. Now i believe that the grand marquis has 1 lo beam and 1 hi beam relay if they are rated at the same amperage you can swap em . The mercury i have has two locations under the hood and under the steering column to the left. In the car it is has a locking tab that you have to pull down to unlock it and it will swing out. In all honesty if you have 20 bucks and want to invest it i would suggest buying an repair guide either way good luck.

most likely cause is the headlamp switch.be sure to check the connector for any melted wires.
